Never heard of him meself, but there are two quite different accounts of his death...
From crash.net - It is understood that Robin died of natural causes in his sleep at a hotel in Belgium, while travelling with his team en route to Spa-Francorchamps.
From the Beeb - Two women have been arrested after a British motor racing boss was found dead in a shower at a sadomasochistic sex club in Belgium.
Whatever, RIP
